O$e!ti%e

This tutorial &o!uses on the use o& O'net(sPro$e!t Editor

The Pro$e!t Editor will allow you to )ui!kly

!reate* simulate* and analy+e the 'er&orman!eo& a !om'uter network

By the end o& this tutorial you should e aleto:

Build the network )ui!kly ,olle!t statisti!s aout network(s 'er&orman!e Analyze these statistics

There are three way to !reate network
